GRAIN-BINDING MECHANISM.

SPECIFICATION forming. part of Letters Patent No. 260,668, dated July 4, 1882,

Application filed April 23,1881. (ModeL) I To all whom it may concern Be-it known that 1, JOHN S. DAVIS, a citizen of the United States, of Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Grain- Binding Mechanism, of which the following is a specification.

The first branch of my invention relates to the method of conveying the grain from the [0 platform, upon which itfalls whenfirst cut,

to a suitable receptacle. I

The particular objects of this branch of my invention are to even the butts of thegrain, and to adapt this equalizing device to the varyingconditionsunder which it is required to. operate, such as variation; in the length of the grain, in the condition of the wind, and in the inclination of the ground to be traversed. These ends Iattain by-means of a wind-board or butt-guide pivoted to a fender or support,

constituting a portion of the inner divider or' equivalent part of the structureot' themachine, extending substantially parallel with the cutting apparatus, but capable of being adjusted z 5 on its hinges transversely thereto over the surface or incline traversed by the grain from the cutting apparatus to the receptacle. This butt-guide is held in the desired relation to the other parts by means of a suitable adjustable o locking device.

The object of the next part of my invention is to provide a space or chamber in which the cut grain may bestraightened and arranged with its stalks parallel to each other before its 3 5 delivery to the binding-receptacle. These ends I attain by employing an endlessapron or carrier, which conveys the grain, when first cut, against a cut-off moving intermittingly at proper intervals, so as to constitute an abutment 4o againstwliich the grain is carried and straightened by the movement of the carrier. A space or chamber clear fromithe falling grain, for effecting this accumulation and straightening of the grain, is obtained by extending the carrier 5 beyond the inner divider and organizing the cut-ofli'n proper'relation thereto. 'lhi's straightening operation is further assisted by a packer consisting of arms rotating in slots in the cut ofiorbetween rods constitutin git, and bymeans of a presser-bar, between which and the cut-off the grain passes through the packer to the binding-receptacle.

The next part of my invention relates to the compression of the gavel. Its object is to enable the compressor to act with equal forceon gavels differing in size-in other words,'to accommodate itself to gavels of dili'erent sizes. This end-I attain by combining with the binding-arm a hinged compressor and mechanism Which automatically locks the compressor as the binding-arm startsin its'forward movement. The next branch of my invention relates to r the method of throwing the binding mechanism into action, its object being to'automatically regulate the'size of the gavel and to secure bundles of uniformsize. This end I attain by i so organizing the mechanism that a definite amount of grain fed into the receptacle by the packer produces suflicient tension on the binding material to throw the binding mechanism into'action, the parts being automatically restored to their normal'position for repetition of the operation after the discharge of the bound bundle. i

Another branch of my invention relates to the method of tying a knot, the organization of mechanism for which purpose is hereinafter fully set forth. V

Other branches of my invention relate 'to the mechanism for holding and compressing the gavel while being bound, and to mechanism for discharging the bound gavel.

My invention mainly consists in novel coinbinations, constructions, or organizationsofold instrumentalities. r v8 5 The subject-matter claimed is particularly designated'in the claims at the end of this specification. T

The accompanying drawings represent my various improvements as embodied in one ma- 9o chine in the best way now known to me. The details of construction of my invention may, however, be modified in variousways without departing from the principle of my invention, and some of my improvements maybe used 5 without the others, and in machines differing in construction and organization from the one herein represented.

My invention contemplates the use of the most approved harvesting mechanism of the present day, the construction and operation of which are wellknown to those skilled in the art to which this invention appertains, and the details of which need not therefore be fully described here.

Figure 1 represents a plan or top view of so much of my improved machine as is necessary to illustrate the subject-matter herein claimed. Fig. 2 is a view in elevation, partly in vertical longitudinal section, on the line 2 2 of Fig. 1; Fig.3, asimilar view and section on the line 3 3 of Fig. 1; Fig. 4, a view in elevation of the binding mechanism as seen from the back or discharging end, with the shipping-pulley shown in vertical longitudinal central section on the line 4 4 of Fig. 1. Fig. 5 represents a front elevation, showing a detailed view of this shipping mechanism and portions of the compressor and its locking mechanism, partly in section, on the line 5 5 of Fig. 6; Fig. 6, a plan view of the comprcssorlocking mechanlSIll, partly in section, on the line 6 6 of Fig. 5.

Figs. 18 to 25 represent on an enlarged scale the details of the method of forming the knot, Figs. 18,19, 21, 22, 23, and 25 being end elevations of the knotting mechanism, partly in section, on theline 18 18 of Fig. 20, and Figs. 20 and 24 being bottom plan views, partly in section, on the line 20 20 of Fig. 19. Fig. 18 shows the nose of the binder- .arm in its most advanced position, in which it a. bottom plan view, showing the hook in a position midway between the positions shown in at the moment of completing the action of knotting.

The drawings show the mechanism as organized for binding with cord snbstantiallyon the level of the grain-platform. Themechanism is mounted on a suitable main frame, A, provided with a suitable cuttingapparatus, B, behind which is a suitable carrier or endless apron, (shown as consisting of a series ofseparate endless bolts, 0,) traversing suitable carrying rollers, C C, mounted in suitable bearings on the frame. Spring-teeth D are secured upon the frame between these belts on the grain side, and project inwardly between them, parallel therewith and at substantially the same general level, but projecting slightly above them at the inner ends to prevent the belts from breaking the straws during their temporary lodgment. They are forked or slotted so as to embrace a series of cut-off rods, a, mounted on the shaft E. These springteeth thus serve as clearers and to remove the grain from the apron as it passes between the rods of the cut-ott'.

Under the organization shown, the carrier and cut-oft are intermittingly and harmoniously actuated by mechanism hereinafter described, which operates them alternately, the cut-off being elevated and maintained in its operative position while the carrier is inoperative, and vice versa.

A packer, F, consisting of a series of S- shaped arms mounted in pairs on a shaft, F, rotates between the cut-31f rods and through slots in the binding-receptacle G. In this instance the packer is shown as so organized as to rotate continuously, while the endless apron and cut-oh" rotate intermittingly. The inner divider is extended upward, so as to form a shield or fender, B, to which a butt-guide, I, is secured by hinges 11. By means of this hinged connection between the butt-guide and divider-heel orlateral projection the upper end of the butt-guide is free to be moved backward or forward, as desired, and can be held in any desired position by a locking-detent consisting of a lockin -spring, 1, or other equivalent device, within easy reach of the driver when in his seat on the machine. The butt-guide moves over and close to a way or tloor, 1, extending from the level of the carrier to the upper edge of the grain-receptacle, at about the same angle as the cut-oft when in its lowest position, forming a part of the surface over ITO which the cut grain traverses. In passing over this floor the butts of grain rub against the butt-guide, which pushes in the projecting ends and causes the butts to lie with their ends smooth and even in a way that is readily understood.

A pressure-bar, J, mounted on spring-arms j, hinged to or otherwise suitably connected with the cross-bar lc-which, under the organization shown, constitutes a binder-arm shaftof the main frame, normally rests upon the butt-guide and upon a fixed shield, j, at the back of the platform, being thus held at a suitable level above the platform.

The carrier, clearer, and cut-off, it will be observed, extend inward some distance beyond the fender to which the butt-guide is hinged, or, in other words, the inner edge of the cutting apparatus, so as to leave a space or chamber in which the grain may accumulate and its stalks be arranged parallel to each other before it is fed to the receptacle.

The operation of the apparatus so far as above described is as follows: The grain as it is cut falls upon the carrier, which conveys it into the straightening-chamber above mentioned, where the continued motion of the apron forces the accumulating grain gratinally up the inclined surface afforded by the cut-off rods, straightening it as it rises. The pressure-bar serves to prevent the grain from rising or being blown away. The straightening of the gavel is also facilitated by the movement of the packer, which tends slightly to retard the grain during the first part of its ascent, until ithas accumulated a certain amount of pressure from the grain behind it.

In Figs. 1 and 2 of the drawings the parts are shown in the position they occupy while thegrain is being fed into the receptacle, the

cut-off being'depressed. -When the packer has forced enough grain into the receptacle to form a gavel of the size desired,--the carrier is automatically stopped by mechanism hereinafter described, and the cut-off rises, so as to prevent the passage of any more grain into the receptacle, the cut grain mainly falling upon the now stationaryearrier.

One object of my invention is to diminish the power requiredto drive the machine as much as practicable, and one of the methods employed by me in attaining this end is to cause the various partsto move successively, the apron being stopped while the binding is progressing, and vice versa.

I After thegavel is bound and the bindingarm retracted to its normal position for the reception of a fresh one, the cut-off descends, the apron starts, and a fresh gavel is fed into the receptacle.

The binding-arm K is shown as mounted on a rock-shaft, 7r, constituting a cross-bar,.passing through a tubular frame or support on which some of the binding appurtenances are mounted. The binder arm may be connected with its rock-shaft by a collar, a set-screw, or

other equivalent lockin g mechanism, which permits it to be swung around the arm to vary its relation to the other portions of themechanism, and thus secure its proper adjustment relatively to the twister or knotter, as well as to the driving mechanism and other parts of the apparatus.

Under the organiz;-1tion-shown, gavels of uniform size are fed into the receptacle, and a fixed compressor would therefore exert a substantially uniform degree of pressure upon them while being bound.

To adapt my apparatus to exert-an equal pressure upon gavels of different sizes, 1 form the compressor L of a V shape in outline, with the branch next the grain somewhat concave, and connect this curved end by a pivot, l, to the binder-arm a short distance from its forward end.

The rear end of the compressor is provided with ratchet notches, and slides endwise through a guide, Z, in the binder-arm, so that as the gavel is accumulated underneath by the packer it gradually rises as the tension of the bundle is sufficient to overcome the weight of the compressor or the force with which it is held down.

. A spring-bolt, l, on the binder-arm is normally held out of contact with the ratchet of the compressor by a fixed stop on the frame;

but as soon as thebinder-arm commences its forward movement toencircle the gavel the compressor securely in the position'it may then occupy, holding it rigidly during the closing of the binder-arm upon the gaveL- (This device is fully shown in Figs. 2, 5, and-6.)

My binder belongs to that class in which the binding mechanism is automatically thrown into action by the strain of the gavel itself upon the binding material, and is automatically thrown out of action after each bundle is bound with its parts in the normal position for the reception of the succeeding bundle. The binding-cord m is wound on a suitable spool, M, revolving on a pivot, m, and maintained under proper tension, preferably by a friction-brake, M, bearing with the force-of a weight or spring, in a well-known way, upon the surface of the bindingmaterial itself. The binding material passes from the spool through tension-pulley the cord is led through an eye, k', in the arm, and through a slot therein, and out through the nose of thearm to the knotting mechanism. (See Figs. 1, 2', and 18.) As the packer forces the grain into the receptacle the cord is pressed back by it and tight- ICC ened, thus drawing more binding material from the spool and turning the tension-pulley forward.

A clutch-disk, O, fastened to a pinion, 0, turns freely on a shaft, 0, capable of sliding freely endwise in its bearings. Whenin proper position a clutch-tooth, 0, on the disk en' gages with the ratchet-teeth of the tension-pulley N, and is consequently caused to turn with it. This movement also turns the pinion 0, which gears witha raclgp, on a radius-bar, P, mounted on a rock-shaft,p,which is provided with a tripping-toe,'P. A recoil-spring, 1)", tends to restore the parts to their normal condition when the clutchisungeared. The range of motion of this radius-bar may be regulated by means of a pimp, taken into a series of holes, a slot and set-screw, or other well-known adjustable stop mechanism, and this whole mechanism regulates the size of the gavels by stopping and startingthe binding mechanism, as will be hereinafter explained. The sliding shaft 0' is concentric with the combined starting and tension pulley, its clutch-disk, and pinion. Its spring 0 tends to force thecluteh normally into contact with the tension-pulley. A rocking lever, O, pivoted at one end to the shaft 0, carries a friction-roller, r,which, when the knotting mechanism is at rest, takes into a notch in an intermittingly actuated main gear-wheel, R, preventing it from being suddenly moved, and allowing the clutch to be in engagement with the tension-pulley, whereby the rotary movement of the pulley is imparted to the pinion and starting mechanism. When the wheel R starts and the binder-arm commences to descend, the roller 1' rides out of its notch, communicating an endwise movement to the shaft 0', which disengages the clutch 0 from the tension-pulley, leaving the pulley free to revolve and pay off a sufficient amount of string to encircle the bundle, while the starting mechanism is restored to its normal positionfby the springp.

The organization shown is such that the movement of about one-third of the amount of string necessary to encircle the bundle will rotate the starting-pulley far enough to actuate thestartingmechanism. Thepulley then being disengaged from the clutch is free to pay off the other two-thirds or any required amount drawn from it by the binder-arm. Under this organization the strain upon the binding-cord produced by the incoming grain operates the starting mechanism and throws the binderinto gear, and then disconnects the starting mechanism, asa conscquenceof which organization the amount of binding material paid out is simply dependent upon the size of the bundle, and the circumference of the tension-pulley need have no fixed relation to the circumference of the bundle. 0n the contrary, were the organization such that the feed was positive-that is, were a certain amount paid out at each revolution of the main driving-gearthe amount required to encircle the bundles would be greater or less than the fixed amount of the feed, as the size of the bundles varied, and consequently the feeding and starting mechanisms would be thrown out of time and the organization disarranged.

It will also be noticed that the organization is such that the starting-pulley may be used simply as such, or as a tension device and a means of starting the binding mechanism; but I prefer to have it act in both capacities.

Before describing the operation of the machine further, I will now set forth the manner in which the mechanism is connected and actuated. The arrows show the direction of rotation of the gears.

A shaft, q, mounted on the frame and driven from the main driving-wheel in any suitable well-known way, carries a spur-gear, Q, meshing into a spur-wheel, F,on the packer-shaft F, to which itimpartsa continuous rotary motion when in gear. The gearing may be disconnected from the driving-power by a shipping-clutch, in one of the usual well-known ways. The spur-wheel Q drives the beforementioned gear-wheel R, and as this wheel actuates the binding mechanism proper I call it the binder gear-wheel. This gear is deprived of three or four of its teeth, so that when this mutilated portion comes opposite the driving-gear Q the binder gear-wheel may remain at rest and out of'gear while the driving-gear Q revolves. The position of the parts when occupyiugihis relation is that represented in the drawings. (See particularly Fig. 2, which shows the binder-arm elevated, the grain being fed into the receptacle by the packer, while the binding mechanism proper is out of grar.)

A spur-gear, S, mounted on the frame has three or four of its teeth removed on opposite sides. A pitman, S, pivoted at one end at s to the side of this mutilated gear-which is, in fact, a crank-wheel-is pivoted at theother end to a rock-arm, E connected by a link, E to a rock-arm, E, mounted on the shaft E. The arm E and link E are connected by the wellknown rule-joint, so that when operated on by the pitman and brought into a straight line, as shown by dotted lines in Fig. 3, the arm E is firmly locked against any pressure of the grain against the cut-off rods during the operation of'binding. The shaft E extends clear through the machine, is mounted in suitable hearings on the frame, and carries on it at its rear end a sliding spring-clutch, E, of wellknown construction, which clutch throws the carrying-roller 0 into or out of gear, as required, this carrier being driven by a belt, 0, from adriving'pulley, F, mounted on the packer-shaft. As shown in Fig. 1, this springclutch is connected with a sliding collar, a", which is supported on the shaft E, and is normally held against movement endwise of the shaft by a spring, b*. When the shaft E is rocked to elevate the cut-off the clutch-collar a is shifted outward by the action of a cam,

0", against the pressure of the spring b and 1 the clutch E is disengaged from the looselymounted pulley on the carrier-roller, thus leav ing the pulley free to rotate as actuated from the packer-shaft without operating the carrier. The organization of the shifted mechanism above described, and cooperating mechanism,

is such that with the partsin the position shown is thrown into operation and the binder-arm begins to advance to surround the bundle the cut-oft rods are thrown up and the carrier thrown out of gear, and remains out until the binding operation is completed and the binderarm has resumed its 'normal position, when the cut-off swings back, the carrier is thrown into gear, and the feeding of the grain into the receptacle is resumed.

An adjustable tooth or spring-actuated locking-bolt, t,'is mounted on the outer face of the binder gear-wheel B, so thatit may he slid endwise in radial guides thereon. VVh'en free to move, as presently to be explained, this bolt is thrust forward by means of the spring 15,

and is caused to engage with one of the spurs or teeth Q Q, projecting from the outer face of the driving-gear Q. This spring-bolt serves to engage the'binder-gear during one revolution with the driving-gear. It is normally held in a retracted position against the action of its spring by means of a lever, T, rocking on a pivot, 15, by which it is' supported between its ends on the inner face of the binder-gear. One end of this lever engages a stud on the spring locking-bolt, which stud passes through a slot in the binder-gear, and the other end is normally held by a locking-catch, t, carried by a rocking shipping-lever, T, actuated by the tripping-toe P, hereinbefore described, which strikes the stud T at the outer end of this shipping-lever. A fixedpam, T, on the frame, and partially surrounding the hub of the binder gear-wheel, acts on the lever T to retract thespring locking-bolt t, and leaves this bolt-controlling lever dogged by the catch of the shipping lever T at the end of a revolution of the binder gear-wheel, and atthe time that the toothless portion of this wheel is opposite the driving-gear.

The binder-arm is actuated by means of a sector-crank, K, fastened on the rock-shaft 7c. The sector-crank is provided with a slot, k,in which a pivot-pin, k, on pitman K plays. The opposite end of this pitman is connected with a crank-pin, K, by means of an adjustable connection of well-known construction, which permits the length of the pitman to be varied to'seeure the necessary relation to the various parts of the mechanism. The slot in the sector-crank allowsthe binder-arm to remain'stationary at the terminal of its forward movement during the interval of the tying of theknot. Duringthisintermission the binderarm is positively locked by means of a springdeteut, KW, taking into a notch on the seetorcrank. J nst previous to the commencement of the backward'movement of the binder-arm the pitman-moves upward in its slot, shoving before itatripping-slide, K workin gin suitable guides on the interface of the sector-crank,

(see Fig. 3,) and releases the spring-catch'from the notch, thus leaving the biuder'arm free to rise.

.The grain-receptacle may be considered as consisting essentially of a V-shaped trough,

one side being composed of an inclined board or shield, G, suitably perforated, the other slde consisting of a series of retaining-teeth,u,

mounted on a rock-shaft, U, and capable of being adjusted and clamped'thereon in the desired relation to the-other parts. The nose of the binder-arm works in a slot in the inclined side of the binding-receptacle, and passes beneath the knotting'mechanism to directthe cord thereto by a suitable guideway, as soon to be explained.

, A kicker ordischarge-arm, U, is mounted on the rock-shaft U, so as to lie within a slot in the receptacle and parallel with the binderarm. The rock-shaft, kicker, and retainingteeth are normally locked in position to retain the gavel in the receptacle by means of a curved locking-lever, U, normally held in position by a rocking spring-latch,U, (see Figs. 3 and 9,) which latch is released at proper intervals by a pin, U, on the outside of the actuatinggear striking the toe U of the spring-latch. (See Figs. 3, 4, and 9.) When released a tappet, V, on the rock-shaft is struck by a corresponding projection, v, on the inner side of the same wheel,-thus rocking the shaft throwing the retaining-teeth down and the kicker up, so as to discharge the bound bundle as the binder-arm rises to resume its normal elevated position. At the proper time a sector-gear, 11", on the inner side of the actuating-lever engages the teeth 22 of a sector-gear mounted on the rock-shaft U, and restores the kicker, retaining-teeth, and locking-latch to their normal position.

A retaininglever, W, rocking on a pivot, 10, just beneath the binder-arm'shat't, is'provided with-a coiled spring, w, which normally holds it'pressed forward and downward, so as to retain the gavel while being bound; The central retaining-tooth, a, abuts against the lowerouter end of-this lever,(see Figs; 2 and 4,) and looks it positively until therock-shaft U is released for the discharge of the gavel," when it moves out of the way and the spring-l retainer yields toallow the gavel to pass as it is thrown out by the kicker, the spring returning the retainer as soon as the gavel has passed.

ICC

Instead of a single retaining-lever, as shown, 1

ing material to the knotter as the nose of the binder-arm passes underneath the shieldand knotter. The knot is formed by a tying-bill, Y,

mounted on a shaft, 3 and having imparted to it first a backward rotary movement of about a quarter of a circle from its normal position, and then a forward rotation of about a circle and a quarter, so as to bring it back to the position from whence it started, the tyingbill always revolving in the same vertical plane.

The main portion of the tying-bill is of a conical form, constituting a volute or spiral of about one turn, secured to a tubular shaft, 1, revolving in suitable bearings, 2 3. A movable jaw, 4, rocks in the plane of the tying-bill shaft on a pivot, 5, its projecting end being pin-jointed to a rod, 6, capable of moving endwise in the tubular shaft 1 of the main portion of the tying-bill. A spiral spring, 7, inside this shaft tends to force the rod outward, so as normally to keep the jaws of the tying-bill tightly closed. A stud, 8, on the side of this slide -rod, during a portion of its revolution, rides over an incline, 9, on the side of the hearing 2, which retracts the rod and opens the bill for the admission of the tying-cord, as hereinafter more fully explained.

The tying-bill is driven by means of a spurpinion, 10, on the end of its shaft 3 meshing alternately with the sector-gears 11 12 on the inner side of the actuating-gear B, hereinbefore described. A spring, 13, bearingin a notch on an enlargement, 14, of this shaft serves to lock and prevent the turning of the tying-bill until the proper moment. be attained by means ofa projecting tooth, 15, on the tying-bill shaft, which tooth slides on a guide-flange, 16, on the inner surface of the actuating-wheel It, which latter plan I prefer, as by it the tying-bill is positively held and released at the proper time.

A driving-pin, 17, on the enlarged portion of the tying-bill shaft(i nits revolution) strikes a corresponding pin, 18, on a bell-crank lever, 19, pin-jointed to a rod, 20, capable of sliding freely'endwise in its bearings, and carrying a shearing clamp-head, 21. The sleeve 22, to which this lever is pin-jointed, niaybeadjnsted on the rod by means of a screw, or in other well-known ways, to vary the range of motion of the knife. The pin 17 moves the clamphead 21. outwardly, and then releases it, it being suddenly retracted by a coil-spring, 2 3, on the rod, draws the cord against the stationary knife 24, and at the same time clamps the severed end against the-fixed clam ping-face 25, back of the knife, in a manner clearly shown in the drawings.

The shearing clamp head moves transversely to the plane of the tying-bill to sever the cord at the propermoment. One end of the bindingcordis securely held bybeingjammed between the clamp and the surface with which it is in contact in a \vell known way, the other end being of course held by the nose of the hinding-arm. In its forward movement the hind- The same end may ingarm, after encircling the gavel, passes under and beyond the tying-billand clamp, so that the cord. lies in the notch 26 of the clamp head and in the neck 27 under the tying-bill, and in or above a hook, 00, of the slot 00, the binding-arm being at this moment securely locked by the dogging of the sector-crank K, above described.

As the nose of the binder-arm passes under the tying-bill a sector-rack, 12, of two teeth, on the inner side of the main actuating-gear B, engages the pinion 10 on the tying-bill shaft, and gives it a quarter backward turn, bringing it to the position shown in Fig. 10, where it will be observed that the bill has passed outside of and beyond both bights of the knotting-cord.

The hooked projection 30-011 the side of the slot 00 catches and prevents the cord from dropping too low to be properly engaged by the bill-hook in case of any siackness orinsufficient tension, its operation being clearly shown in Fig. 20.

Just about the timethe binder-arm is locked the internal sector-gear, .11, on the inner side of the actuating-gear R, meshes with the pinion 10, above mentioned, on the tying-bill shaft, and gives it a forward revolution of a circle and a quarter, carrying it successively through the stages shown in Figs. 21 to 25 of the drawings, which show the various positions of the parts so clearly as scarcely to require description.

As the tying-bill rises after the backward movement above mentioned it hooks over both ends of the cord and carries them around to the position shown in Fig. 21, the bight of the binding-cord previously lying underneath the neck of the tying-bill gradually slipping off therefrom behind the portion engaged by the point ot'thc hook. Itis arrested and held from slipping otf before the bill seizes thecord, which would spoil the knot, by means of a shoulder, 28, in the bill. At this moment the stud 8 on the tying-bill shaft slides over the incline 9 on the bearing 2. Consequently the endwise movement of the slide-rod above mentioned causes the tying-bill to open, as shown in Figs. 13 and 22, to receive both ends ot'the binding-cord between the tying-bill and the cutter. As the stud 8 passes the incline 9 the sliding rod 6 is released and shoved forward by its spring, so as to (lose the jaws of the tying-bili on the cord. Atthe sametimeits outer end pushes the loops from otf the shoulders 28, enabling them to slip toward the point of the bill, as shown in Fig. 23; As the parts assume the position shown in this figure the clamp is thrust forward into the position shown in Fig. 14, the cord slipping from the notch 26into the space between the projecting shoulder of the shearing-clamp 21 and the parts. by this time assuming the. position shown in Fig. 25, at which point the bundle is discharged by the kicker, and the cord there-.

by pulled from between the jaws, leaving the parts in position for the nextstroke, they being locked in this position by the devices above described;

As the tying bill requires somewhat nice workmanship, I propose making its parts of cast-steel and to enable these parts readily to beremoved and replaced the tying-bill shaft is made in two sections, withflan-ges on the abutting ends, which ends are countersunk or counterbored, so as to insure accurate fitting, and held together by clamp-screws.
